General Characterization
Desmophen VPLS 2388 is a flexibilizing hydroxyl-bearing polyester.
It is suitable for use as a co-reactant, primarily with Desmodur® N, in the formulation of two-component polyurethane coatings for plastics, characterized by their resistance to accelerated and outdoor weathering, high film elasticity and good tar resistance; also in the flexibilization of hard coatings, e.g. in industrial applications.

Storage Conditions
Desmophen VPLS 2388 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. The product is somewhat hygroscopic. The product is sensitive to moisture. Storage at higher temperatures will result in an increase of color and viscosity. Recommended storage temperature is 5º-30ºC.
